, invention relates tocertainclassesoif plumbing fixtures such asshower bath traps andthe like where a drain pipe or other cong duitis mounted in tile,"--' concreteor other flooring and arranged fiush therewith.

" Oneof the objects of the invention is to prevideaconstruction-whichwill permit the V drain-pipe to-be accurately positioned in the N1 freehand permanently secured tQ'the pipe "ew'hetheror not-the latter is exactly perpenjdiculafto thefloori f 1 g 3 Anotherf obj ect 5 is 4' to construct a shower batlitrap havingafswivel joint connection 7 Y towh'i'chthe strainer tube is attached.

A further object is to provide a 'de'vice in which "the strainer tube 5 may *bev removed from the pipeit desired 'a' fter the floor is Another object is to provide improved meansjior draining into'the trapany water leaking into'thefloorf r Q 7 These and otherxobjects are'attained with the'novelj construction'hereinaftermore fully Q described; and illustrated in the accomp anying drawingsfwherein l? i I Figure 1 section;through the trap I showingthe positionofthesame in the floor; Fig'uref2 is a plan' view of the leveling Ir a;

I In accordance with my invention, the trap 1"O 'has formed at'its .upper end the spherical I seat 11 into whichfits a separate leveling ring 12., Thering has a curved lower surface13 correspondin to the seat 11 which enables the ring to e given a unlversal rocking movement with respect to the trap. The ring has interior threads 14 for receiving the threa-ded'drain tube '15 which extends up wardly therefrom to the level of the floor.

The upper end of the trap '10 extends up wardly and outwardly beyond thespherical seatforming the top flange 16. Adjacent the sphericalseat the flange has an} inwardly extending annular shoulder 17 forming between the same and the; ring a recess, the

bottomil8 of which is larger than the neck 19. Below the seat 11 the walls of the trap 10 are provided with internal threads 20.- The *iriainbody portion of the trap may be made in'a ny suitable manner to provide a return bend to theconduit in accordancewith the usual practice. As shown the trap extends downwardly below the seat for a certain distance and has an outlet branch 23 eX- tending upwardly to theoutlet flange 24, es r.

line A'-- A.v r p The leveling ring :12 i s-provided with a tablishing the waterlevel in the trap at the series of drain slots 25 cut through the in terior threads let at circumferentially spaced POIDtSL: vThis permits any water which may collectabove the leveling. ring and outside of the drain tube 15 to drain through into the trap; The leveling ring 13 has anannular groove 27 aboveithe threads l l and 1- a curvedsurface 28below the threads; Supportecl'within theannulargroove 27 is a tubulari member 29 which telescopicallyengages a second tubular element 30, the two forniing an protecting'seal 011 the outside of the threaded drain tube 15/ The upper end of the draintube flares outwardly at 30" and h as at 1ts top portion the annular groove 31 for receivingthe outer edge of the strainer-'32,

which latter as shown has a depressed center portion '33. The strainer 32 is removably secured to the'flange 30 by machine screws 34 orother means.

manner. #I'nshower bath construction it is universal-practice 'to use sheetlead beneath the floor and this is illustratedin the drawings by the reference numeral 37. The sheet leadiscut away'to'form an opening registering with the trap-and the edges 38 of the aperture so formed are bent around the au- 'nular-shoulder17 which surrounds the level- 'ing"ring- 112. Ehe'joint between the sheet lead and the trap body'is then made water Jed l leveling Before this: jointisfsealed,

however, the drain tubeis'threaded into the leveling mingle and the latter is swiveled on the spherical seat 11 until the top of the drain tubeand the strainer;32 is exactly level: By reasonof this universal joint the drain i tube may be leveled after the trap-is installed gin positionand any inaccuracy in alignment of the trap when connecting the sameto the plumbing may be easilyicompensated by adjusting the." leveling ring.

i After the levelingringis securedinfinal,

1 position by the calking lead the concrete base 1' 39 0f the floor maycgbe poured around the, drain tube but this concrete Will be held'out of' c ontactwith. the threaded portion ofthe draintubebythe tubes 29 and 30; 1 Itis usual toprovide the-surfaceo'f the floor With tile which is indicated at 40 and arrangedjto be exact ly'flush withrthe topofthefdrain tube. With the constructionas above described i there are many advantages over the usual 7 constructionof showeribathtrap; The chiefadvantage resides inthe factthatiithe ads justableleveling-ring permits: accurate level-f ing of the upper'surface ofthedrain tube, regardless of any misalignment inthe'body:

of the trapzwhiohis connected'to the restof' the plumbing. Another: advantage is I that V plumbinggmay be tested previous to the calk ingofcthe leveling ring in finalfposition, it 7 is nec'essary to p'rovide'an arrangem'entfor sealing the upper end ofthe trap. With my construction this can be "done by 'removing I the leveling ring 12 and inserting a plug 41 threaded to engage the threads" 20 in the upper portion of the trap. After the testing is completed theplug 41 isiemove'dand the threads 20 have no further utility}.-
